C ABI

Definitions

1. C ABI is the binary calling convention and data layout contract used by C-compatible code. It is commonly used for linking libraries across languages and compilers, where teams need predictable behavior under real workloads rather than toy examples. Practitioners pay attention to symbol naming, memory layout, and platform differences, because those factors usually determine whether the approach improves quality, latency, reliability, or operating cost in production.

   In plain English: C ABI is a software engineering concept that helps developers structure code, run systems, or debug behavior more reliably in real projects.

   Example: "We standardized on C ABI in this service because the old approach was fragile under load; the new implementation reduced operational surprises and made the codebase easier for the next engineer to reason about."
